Question

attach file need help

Answer 1

that's a little odd, these are sets, not functions...

Answer 2

fog = {(1,0),(2,10)}
gof = {(2,-7)}

Answer 3

Evern can u show step by step?

Answer 4

sure, think of the function like a program ... input of a sort gives ou a certain out put.
So,we look at the first function all possible outputs -7,1,2 (each has a corresponding input) from f.These form the basis for the input of g. but -7 does not exits as input in g.therefore that cannot be part of the net function.1 and 2 on the other hand have different associated outputs in the case of g ..which gives us the net gof output.

Sorry: i htink i mixed up the the labels for the answer i.e. gof <-> fog

Answer 5

fog = {(2,-7)}
gof = {(1,0),(2,10)}
?

Answer 6

yes,you got it the variables always go through the function on the right first

Answer 7

the answer is correct?
fog = {(2,-7)}
gof = {(1,0),(2,10)}
?

Answer 8

yes

Answer 9

ty

Answer 10

can u help me one more?

Answer 11

sure, but you have to show how you've tried it first before i do anything

Answer 12

I will send you my work

Answer 13

fog= I'm not sure
gof= doesn't exit

Answer 14

fog={(3.-3),(2,-3)}?

Answer 15

is that a -3 in g

Answer 16

which one?

Answer 17

g -2nd term...where'd you go?

Answer 18

the set o g is {(1,0),(-3,1),(2,1)}

Answer 19

on the picture
gof= 1 0 domain of f
1 -3 range f, domain g
0 1 1 range g

Answer 20

fog ={(1,-3),(3,1)(2,1),} which is a function

Answer 21

why not -3?

Answer 22

fog = 1 3 2 domain of g
0 1 1 range g, domain f
1 -3 range f
why not -3?

Answer 23

ahhh...you've accidently written 3 on the left hand side fog column

Answer 24

yes
fog = 1 -3 2 domain of g
0 1 1 range g, domain f
1 -3 range f
than, I think only {(2,1)?

Answer 25

why both 2 and 3 produce the same output

Answer 26

2 and -3

Answer 27

fog =(2,-3)?

Answer 28

valid inputs for fog 1->0->-3 , 2->1->1 ,-3 ->1 ->1

Answer 29

oK, ty

Answer 30

how gof ?

Answer 31

gof= 1 0 domain of f
1 -3 range f, domain g
0 1 1 range g

Answer 32

gof={(1,0),(0,1)}
